"American Idol" is always an emotional experience for the contestants, but Tuesday night's show may prove to be even more emotional for contestant David Cook. The rocker contestant's brother, Adam Cook, who is battling brain cancer will attend the show.

Adam, and his wife Kendra, plan on attending both Tuesday and Wednesday night's episodes of "American Idol." Adam, 36, lives in Terre Haute, Indiana, and doctors initially told him his condition was too delicate to fly commercially.

News spread quickly of Adam's condition and the town rallied behind Adam, who is a lawyer, but is undergoing chemotherapy for his second diagnosis of brain cancer which has spread to his spine. Adam and Kendra have two children, ages 5 and 6.

The town arranged for a private Learjet, complete with private medic and flight nurse, to take Adam and Kendra to Los Angeles. A local radio station in Terre Haute is paying for a hotel right across the street from the studio where the "American Idol" contestants perform.

Kendra said David, 25, is excited about his brother coming to see the show. She said she isn't sure what he will be singing, but they have talked about going out to dinner and hanging out.

The remaining seven contestants will sing Tuesday night on "American Idol" on FOX.
